Antenatal depression risk under the NSW SAFE START Strategic Policy: Who is missing out on universal screening?

To examine antenatal depression risk screening coverage under the NSW SAFE START Strategic Policy and to explore maternal and sociodemographic factors associated with under-screening.

Completion rates for the Edinburgh Depression Scale (EDS) were examined in a retrospective dataset of routinely collected antenatal care data including all women who birthed at public health facilities in Sydney Local Health District from 1 October 2019 to 6 August 2020. Potential sociodemographic/clinical factors associated with under-screening were identified using univariate and multivariate logistic regression. Free-text responses regarding reasons for EDS non-completion were examined using qualitative thematic analysis techniques.

A total of 4810 women (96.6%) in our sample (N = 4980) completed antenatal EDS screening; only 170 (3.4%) were not screened or lacked data to indicate that screening had occurred. Multivariate logistic regression analyses showed that women under certain models of antenatal care (public hospital care, private midwife/obstetrician or no formal care), non-English speaking women who required an interpreter, and women whose smoking status during pregnancy was unknown had a higher odds of missing screening. The reasons for EDS non-completion indicated in the electronic medical record revealed language and time/practical constraints to be the most commonly-reported barriers.

Antenatal EDS screening coverage was high in this sample. Refresher training for staff involved can emphasise the need to ensure appropriate screening for women who access shared care in external services (particularly private obstetric care). Additionally, at the service level, improved access to interpreter services and foreign language resources may help minimise EDS under-screening for culturally and linguistically diverse families.
